7.4.1 Clear Autolog?
This function clears the memory of all autologged data. Once the 1522 has
logged 10,000 readings, further automatic logging is prevented until the mem

ory has been cleared. Pressing the CLR button cancels the “Clr Autolog?”
function and advances to the next function. Pressing the ENT button also ad

vances to the next function.
7.4.2 Log Rate
This function configures the rate at which data is stored into the memory of the
1522. The following rates are available: 1, 5, 10, 15, 30, or 60 seconds, 2, 5, 10,
15, 30 or 60 minutes. Scroll through the rates using the Up or Down buttons
until the desired rate is shown and then press the ENT button to select the rate.
The 1522 advances to the next function. Pressing the CLR button at any time
also advances to the next function.
7.4.3 Autolog Label
A label is stored with each logged reading. Up to 25 labels should be
pre-loaded into the unit through the serial port or the infrared dongle prior to
autologging. These labels can then be used to differentiate separate autologging
sessions. The same label is applied to every data point once autologging is initi-
ated. To change this label, autologging must be stopped and a new label se-
lected. When selecting labels, press the ENT button to store the displayed label
or press the CLR button to revert to the previously selected label.
The labels can be pre-loaded using Windows® HyperTerminal or other serial
communications program and the command LBnn=[nnnnnnnn] as described in
Section 8.2.1. The labels can also be pre-loaded using the serial port or the
2374 IR dongle with the 9934 LogWare or 9935 LogWare II software available
by calling an Authorized Service Center (see Section 1.3 on page 4).
7.4.4 Autologged Data Storage
This function stores values to the memory of the unit for future download. Each
reading is stored with units, date, time and label. Up to 10,000 readings can be
stored in memory.
The message "ENT to start log" appears on the 1522 display. Press the ENT
button to begin autologging. Press the CLR button to cancel and advance to the
next function.
After pressing the ENT button the 1522 begins to log data automatically at the
rate specified in the Log Rate (see Section 7.4.2) and with the label chosen in
Autolog Label (see Section 7.4.3). The 1522 display alternates between the
message "ENT to stop log" and "Logging NN% Full" where NN is a number
between 0 and 100 and shows the percentage of memory that contains
autologged data. When data is being logged, all buttons are disabled except for
the ENT button.
